那位高手帮帮忙，帮我翻译一段英文，机器翻不要..感激！
One thousand milliliter of sample was introduced into a given beaker containing 100.0 μg of hexahydrothymol
as internal standard. 10% NaOH was employed to adjust the pH (PH≥1 1).Basic contents of the sample were then extracted 3 times by 50 ml of dichloromethane.The pH of the remaining liquor w as adjusted to a pH o f 2 u sing 6 mol/L H 2SO4, an d acidic contents were extracted as described above. The two extracted liquors were brought together and dried for about 24 h by anhydrous sulfate sodium, and finally evaporated to 1.0ml in K-D (Kudema-Danish evaporator). 1.0 μ1 of the remaining liquor was withdrawn for GC-MS analysis.
Finnigan Voyager was used as analytical tool for gas chromatography-mass spectrometry (GC-MS) analysis, with DB-5 silica capillary column (30 m x 0.25 mm, 0.25 μm). The column temperature was programmed from 50℃ (for 2 min) to 300℃ (for 10min) with a heating-up velocity of 10}C /min, carrier gas of He was 1.0 ml/min, and a split ratio of 20:1. Source temperature was held at 200`C, ionization energy at 70 eV (electron volt). Interpretation of the
resulting chromatograms and mass spectra was performed using NIST (National Institute of Standards and Technology) library.
1）样品原溶液通过50ml的二氯甲烷提取了三次。剩下的液体用6mol/L的硫酸进行中和到ph值为2,并且里面的酸已经通
过上面所说的方法提取了。这两种提取过后的液体一起用无水硫酸钠进行干燥24小时，并最后蒸发到K-D 1.0ml。其中剩余的一毫克将用来做GC-MS分析(气相色谱-质谱联用分析)。
2）Finnigan Voyager和DB-5色谱柱（30米*0.25毫米，0.25微米）是用来做GC-MS分析的一个分析工具。色谱柱的温度被设计为10摄氏度/分钟的速度从50摄氏度（2分钟）上升到300摄氏度（10分钟），氦气是10毫升/分钟，分离率为20:1。源头温度控制在200摄氏度，离子能量为70eV（电子伏特）。色谱气相分析结果的解释是由NIST（国家标准和技术局）图书馆完成的。
太专业了，本人高中理科，但是大学不是化学专业。所以大概意思。请其他高手赐教。谢谢！
